BOTTLE-STO PPER.

SPECIFICATION forming part of Letters Patent No. 350,801, dated October12, 1886.

Application filed J une 19, 1886. Serial No. 205,720. (Model.)

To all whom it may concern.-

Be it known that I, CURTIS W. BUFFUM, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inBottle-Stoppers; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to an improvement in bottle-Stoppers, the ob]l ectbeing to provide a stopper of simple and durable construction and ofsmall initial cost, and to provide a stopper that may be easily andrapidly openedor closed; and with these ends in View my inventionconsists in certain details of construction and combination of parts, aswill be more fully set forth hereinafter.

In the accompanying drawings, Figure 1 is an elevation of the neck of abottle provided with one of my improved Stoppers, constructed inaccordance with my invention. Fig. 2 is a perspective view of myimproved stopper detached from the bottle. Fig. 3 is a side elevationcfa modification, showing the manner of applying myimprovement tobottles already manufactured.

To put my invention into practice I form about the neck a of a bottle,and integral therewith, a coarse screw-thread, b, of steep pitch,elevated or raised abovethe surface, making but one and one-half turnabout the neck a, and provided at either end with a downward and upwardprojection or stop, c. I now provide a light metallic circular band, d,having formed near the ends two small bosses, e, with circular openingsin the center of the same, in which are secured the two bent ends f of awire, g, having attached to the top portion a metallic cap, h, providedon the under side with a circular piece of rubber, fi. This cap hdiffers in no essential feature from those now in common use. Thiscircular band d is now forced over the neck a of the bottle into thegroove formed by the raised screwthread b; as shown at Fig. 1 on thedrawings. By revolving the band d about the screwthread b the cap orstopper 7L is either released or tightened over the mout-h of thebottle. If released, the cap h is thrown back, and, being hinged to thecircular band d, remains attached to the bottle.

When the bottles are already manufactured, I provide a circular metallicband, 7s, divided into sections, and secure the same about the neck ofthebottle by short pins Z. This band k, I also provide with ascrew-thread, m, constructed in the same manner as that beforedescribed. (See Fig. 3.) The band d, cap h, and bent wire g are thesaine as before described.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, ls-

1. The combination of a bottle having its neck provided with aprojecting spiral thread, having an upward and a downward lug, c,thereon, a plain metallic band having bossjournals, and adapted to moveup and down on the said thread and be stopped by the said lugs, and thebail journaled in the said collar and carrying a stopper, substantiallyas specifled.

2. The combination of the sectional band k, having a thread formed aboutthe same, and a means for securing the sections about the neck of abottle, the bent wire g, having attached thereto the cap or stopper h,and metallic band d, as and for the purpose described.
